Question

我正在使用Buildroot 2017.2作为操作系统在Raspberry Pi 3上安装picamera组件。

python -c "import picamera"的输出如下：

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/picamera/__init__.py", line 72, in <module>
    from picamera.exc import (
  File "/usr/lib/python2.7/site-packages/picamera/exc.py", line 41, in <module>
    import picamera.mmal as mmal
  File "/usr/lib/python2.7/site-packages/picamera/mmal.py", line 47, in <module>
    from .bcm_host import VCOS_UNSIGNED
  File "/usr/lib/python2.7/site-packages/picamera/bcm_host.py", line 47, in <module>
    _lib = ct.CDLL('libbcm_host.so')
  File "/usr/lib/python2.7/ctypes/__init__.py", line 362, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: File not found

显示的uname -a信息系统是：

Linux buildroot 4.4.43-v7 #7 SMP Tue Aug 1 17:56:58 CEST 2017 armv7l GNU/Linux

我已设置gpu_mem=128。

可能是什么问题？
